Stewed pears now sold in ounces (4,8)

I believe the answer is:

snow leopards

'ounces' is the definition.
('snow leopard' can be a synonym of 'ounce')

'stewed pears now sold' is the wordplay.
'stewed' is an anagram indicator.
'pears'+'now'+'sold'='pearsnowsold'
'pearsnowsold' is an anagram of 'SNOW-LEOPARDS'.

'in' acts as a link.

I've seen this clue in The Telegraph.
